Question

solve, -9y < 72

Explanation:

Step1: Divide both sides by -9

When dividing an inequality by a negative number, the inequality sign flips. So, we divide both sides of \(-9y < 72\) by \(-9\).
\(\frac{-9y}{-9} > \frac{72}{-9}\)

Step2: Simplify both sides

Simplifying the left side gives \(y\) and simplifying the right side gives \(-8\).
So we get \(y > -8\) (or equivalently \(-8 < y\)).

Answer:

\(y > -8\) (or \(-8 < y\))
